Brown, Columbus, Ind., assignor to Hamilton Cosco, Inc., Columbus, Ind., a corporation of Indiana Filed Jan. 9, 1967, Ser. No. 608,181 7 Claims. (Cl. 108-157) ABSTRACT OF THE DISCLOSURE A shelf structure having a supporting frame and removable shelf in which said shelf provides a supporting surface and said frame provides a support for said shelf and a means for supporting other objects.

BACKGROUND OF THE INVENTION This invention relates to a shelf structure mountable on a floor to ceiling pole or the like having a frame upon which a removable shelf is supported.

SUMMARY OF THE INVENTION According to the preferred form of the invention there is provided a ring-like main frame. A sub-frame is mounted on said main frame and comprises a plurality of spokes having their inner ends interconnected and lying in the general plane of said main frame. Said spokes are connected to the main frame outwardly from their inner ends and project downwardly therefrom with their outer ends being interconnected below the plane of said main frame.

A shelf is carried on said spokes and is provided with a plurality of downwardly projecting fingers having slots formed therein for releasably locking it in position on said spokes.

The frame and shelf assembly are adapted to be mounted on a floor to ceiling pole or the like by a support member connected to the inner ends of said spokes and projecting outwardly from the main frame.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings illustrate the invention. In such drawings:

FIG. 1 is a side elevation of a shelf structure embodying the invention;

FIG. 2 is a front elevation of the shelf structure shown in FIG. 1;

FIG. 3 is a plan view of the shelf structure shown in FIG. 1 but with portions thereof being broken away; and

FIG. 4 is an enlarged fragmentary vertical section taken on the line 4-4 of FIG. 3.

DESCRIPTION OF THE PREFERRED EMBODIMENT As shown, the main frame for the shelf assembly comprises a ring of rod stock. The sub-frame, which is also formed from rod stock, comprises pairs of spokes 12 radiating outwardly from the center of ring 10. The inner ends of the spokes in each pair are interconnected by a transverse stretch 14 at the center of the ring with said stretches being joined together on the diameter of said ring. The spokes 12 project outwardly from the center of the ring 10 in the general plane of said ring and are connected to said ring adjacent their outer ends. As shown in FIG. 2, the spokes are provided with legs 15 extending downwardly from their connections to the ring and terminating in outwardly projecting arms 16 disposed in a parallel plane below said ring. The outer ends of the arms 16 on each pair of spokes are interconnected outside the circumferential extent of the ring 10 by arcuate stretches 18 which serve as towel bars or the like.

A circular shelf 20 is supported on the spokes 12 within the extent of the ring 10. As shown in FIG. 4, said shelf has a peripheral depending skirt 22 provided with a plurality of circumferentially spaced, downwardly projecting fingers 24. Each of said fingers has an elongated slot 25 extending inwardly from one side thereof for reception over one of the spokes 12. The slots 25 all have their opens ends facing the same direction so that the shelf can be placed on the spokes and then rotated causing the fingers 24 to lockingly engage said spokes for releasably locking the shelf thereon.

The shelf assembly is adapted to be supported in an operative position on a floor to ceiling pole 26 or the like by an L-shaped support 28. As shown in FIG. 1, said support has a horizontal leg 31 secured to the bottom faces of the stretches 14 and projecting outwardly therefrom. The leg 31 projects outwardly beyond the ring 10 and terminates at its outer end in a downwardly projecting leg 32. The support leg 32 is receivable between a pair of opposed clamp plates 34 having a first pair of fingers 35 received around the leg 32 and a second pair of larger fingers 36 received around the pole 26. The clamp plate fingers 35 and 36 are bindingly retained in engagement with the support leg and pole by a screw 38 for thus mounting the shelf assembly in the desired position on the pole.

I claim:

1. A shelf structure comprising a main frame having an open central portion, a sub-frame extending across the central portion of said main frame and connected thereto, a support interconnected to said main frame and projecting outwardly therefrom, and a shelf carried on said subframe and having means lockingly engageable therewith.

2. The invention as set forth in claim 1 in which the central portion of said sub-frame lies in the plane of said main frame and the outer portion of said sub-frame is substantially vertically displaced out of the plane of said main frame.

3. The invention as set forth in claim 1 in which said sub-frame comprises a plurality of spokes interconnected at their inner ends in the plane of said main frame and having their outer ends projecting downwardly from said main frame and interconnected below the plane thereof.

4. A shelf structure comprising a main frame having an open central portion, a sub-frame having a central portion extending across said main frame in the general plane thereof and an outer portion disposed substantially vertically out of the plane of said main frame, a shelf carried on said sub-frame and provided with a plurality of spaced fingers having slots formed therein for reception over the central portion of said sub-frame for releasably locking said shelf thereon, and a support projecting outwardly from said main frame.

5. A shelf structure, comprising a ring, pairs of coplanar spoke members interconnected at their inner ends and connected to said ring adjacent their outer ends, means spaced from said ring interconnecting the outer ends of the spoke members in each of said pairs of spoke members, a support projecting outwardly therefrom from said main frame, and a shelf supported on said spoke members and having means lockingly engageable therewith.

6. A shelf structure, comprising a ring, a plurality of spokes interconnected at their inner ends on a diameter of said ring and connected adjacent their outer ends to said ring, said spokes projecting downwardly from their connections to said ring and having their outer ends interconnected together below the plane of said ring, a shelf carried on said spokes and having means lockingly engageable therewith, and a support projecting outwardly from said ring.
